To all 'whom t may concern:

Be it known that I, THoMAs F. MULLIGAN, a citizen of the United States, residing at Fort Vayne, in `the county of Allen and State of Indiana, have invented certain new and useful Improvements inApparatus for Filling Oil-Cans, of which the following is a specification.

This invention relates to improvements 1n portable apparatus for filling oil cans, and the primary object of the same is to provide an improved device of this character for filling oil cans or other receptacles, and which will automatically cut olf or stop the supply of oil when the can or receptacle is filled to prevent spilling or wasting the oil.

A further object is to provide an improved normally closed discharge nozzle which is adapted to be adjusted by the can or receptacle when the latter is properly positioned to be illed, and improved means for permitting the oil to pass the outlet to be discharged back into the tank when the can is filled or when no can or receptacle is present under the nozzle, thereby preventing waste of oil.

A further object is to provide an improved device of this character which' will be simple, durable and cheap in construction, and elfective and efficient in operation.

To the attainment of these en'ds and the accomplishment of other new and'useful olbjects, as will appear, the invention consists in the features of novelty inthe construction, combination and arrangementof the several parts hereinafter more fully described and shown in the accompanying drawing illustrating the embodiment of the invention, and in which:

Figure 1 is an elevation partly in section of an improved device of this character constructed, in accordance with the 'principles of this invention. Fig. 2 is an enlarged detail sectional view of the discharge nozzle and valve showing the latter in one of its' positions. Fig. 3 is a detail view similar to Fig. 2, showing a modied form of the discharge nozzle and valve. Fig. 4 is an enlarged detail sectional view of the discharge nozzle and valve with the latter in position to permit the fluid to pass the discharge nozzle and to reenter the tank. Fig. 5 is an enlarged detail sectional view of the pump for forcing the liquid from the tank. 6 is an enlarged detail sectional view partly Fig.

in elevation of the support and lifting mechan1sm for the oil can. Fig. 7 is a detail top plan view of the discharge nozzle.I

Referring .more particularly" to the draw-l ing, and in the present exempliication of the invention, the numeral 10 designates the vided adjacent one extremity with a valve `casing 15, which latter is provided with valve seats 16, 17.- Connected to and communicating with the casing 15 is a tubular member 18 which extends to a point in close proximity to the bottom of the tank 10. Valves 19 and 20 are provided to coperate with the respective valve seats 16 and 17, and a communicating passage 21 is provided between the pump cylinder 11 and the casing 15, preferably above the valve seat 17. The valve casing 15 is also provided with a valve seat 22 withwhich the valve'20 cooperates in a manner to be set forth.

The tubular member 13 extends for any desired distance above the top of the tank and is connected by means of a tubular connection 23 to a similar upright tubular member 24', which latter has communication with the tank 10 through an inlet opening in the top thereof, preferably at a point remote from the tubular member 13.

Arranged within the cylinder 11 is a pis-v ton 25 which is provided with a .piston rod 26 having an voperating handle27 secured thereto by means of which the operator. may reciprocate the piston 25 within the cylinder.-

Arranged within the connection 23 between the tubular members 13, 24 is an adjustable nozzle designated generally by the reference numeral 28. This nozzle comprises a casing having apassage 29 therein, which communicates with and forms a coniinuation of the tubular. connection 23. lidably mounted in the casing 28 of the discharge nozzle is a combined nozzle and valve 30 which is provided with a transverse passage 31, and which [passage is adapted to be normally held in a yposition to register with the passage 29 by means of a suitable elastic member 32 situated within the casing 28 and engaging the valve 30, so that in the event of the operation of the pump when no receptacle is in position to receive the li uid from the nozzle, the liquid will not be discharged from the nozzle but will flow back into the tank and thereby prevent waste of the liquid. This valve is A rovided with a tubular portion or nozzle 33 belou'r the passage 31 and arranged within the tubular portion is a partition 34 to divide the nozzle into two passages 35, 36, one of which, preferably the passage 35, is of a diameter somewhat larger tha-n the diameter of the passage 36. The nozzle 33 is provided with an aperture 37 adjacent but out of communication with the passage 31, which extends through the wall thereof and communicates with the passage 35. A similar aperture or opening 38 is provided on the other side of the partition 34, preferably adjacent the aperture 37 and communicates with the passage 36. The valve 30 is adapted to loe-moved upwardly against the tension of the elastic member 32 into the position shown in Fig. 2, so as to move the passage 31 out of register with the passage 29 and cause the apertures 37, 38 to register with the passage 29. Y

The nozzle or tubular extremity of the valve 30 is adapted to slide through a suitable stufling` box 39 and is provided with a circumferential projection 40 secured thereyto beyond the stuffing box. This projection 40 may be provided with a circumferential depending flange 41,and arranged within the flange 41 is a. suitable packing 42.

Supported in any desired or suitable manner adjacent the discharge nozzle is a bracket 43 which. is preferably adjustably secured to the upright tubular member 24 and is `erably bifurcated,'as at 47, and extended as provided with a bearing 44 through which thel stein 45 of a platform or support 46 is adapted. to slide. The bearing .44 is prefat 48 to form spaced ears between which an operating handle or lever 49 is pivotally supported, as at 50. One extremity 51 of the handle 49 projects below the stem' 45 of the platform 46 and engages the extremity thereof so that when the handle 49 is depressed, the platform will be raised.

The receptacle to be filled, such `as an oil can 52, is adapted to be supported upon the platform 46, as shown in Fig. 1, and is so positioned that when the handle 49 is depressed the oil can will be moved from the position shown in full lines in Fig'. 1, to the position shown in dotted lines. As the oil can or receptacle is elevated,the ex- .tremity of the nozzle or valve will enter thee opening in the top thereof, as shown in Fig.l 4, so that the neck of the can will engage the packing 42 upon the projection 40.

A further depression of the handle or lever will raise the can or receptacle 52, and with it the discharge nozzle and valve 30 to force the latter upwardly against the tension of the elastic member 32 to move the passage 31 out of register with the passage`29 and the passages 37, 38 into register with the passage 29 to the position shown in Fig. 2 of the drawing. When in this position the piston 25 may be reciprocated in the cylinder 11. The upward movement of the p1ston 25 will unseat the valve 20 and will also draw the oil from the tank 10 through the tubular member 18 and through the passage 21 into the cylinder 11. As the oil flows into the cylinder 11, the valve 20 will be forced against the seat 22 to close the communicating passage 53. When the piston 25 is forced downwardly in the cylinder, the pressure of the oil will 'seat the valve 20 and the oil will also flow through the communicating passage 53 to unseat the valve 19 and be discharged through the tubular member 13 into the tubular member 23 through the opening 37 and the passage 35 in the nozzle to be discharged into the can or receptacle 52. rlhis operation will be oontinued and the oil will flow into the can until the can has become filled, the oil being prevented from escaping -from the can through this opening by means of the packing 42 and projection 40, which form ,a closure for the can. Any further operation of the piston 25 in a downward direction will create a pressure upon the oil in the can 52, and will force the surplus oil into the passage 36, out of which passage it will flow through the opening 38 to be discharged back into the tank. The can or receptacle having been filled, may be removed from the nozzle by raising the handle 49, which will lower the platform 46, and as the can or receptacle moves downwardly, the elastic member 32 will expand to force the valve 30 and the tubular extremity or nozzle downwardly with the can or receptacle to cause the passage 31 to again move into register with the passage 29 to restablish communication between the tubular members 13 and 24. When this communication has been restablished, it will be apparent that any operation of the piston 25 to force the oil from the tank 10 into the tubular member 13 will cause the oil to flow through the passages 29 and 31 into the tubular member 24, and be discharged back into the tank, the only effect being to create a circulation of the oil Without discharging any of the oil.

The modified form of valve and nozzle as shown in Fig. 3 is particularly adapted for use'when the oil supply is fed by gravity and comprises a body or valve 31u having a tubular portion within which is a partit1on 34*L to divide .the same into .two passages 35a--36, which are provided respectively mismas limiting the movement of the combined; valve and nozzle, and for this' purpose there.

may be provided a slot 54 in the valve and a screw bolt 55 is tapped through the casi 2S to extend into the slot and with its hea 56 against the outside of the casing. The tank 10 may be filled in any suitable manner, but preferably throu h an opening 57 in the top thereof be ow the dis-A charge nozzle, and iremovably arranged within this opening is a strainer 58. This opening also serves as a` means whereby any oil which may be spilled from the can or nozzle will be discharged back into the tank.y
